If hydrogen is removed from a substance, which process is it generally considered to be?

Answer and explanation

Correct answer: Oxidation

According to the classical definitions of redox reactions, removal of hydrogen from a substance is oxidation, while addition of hydrogen is reduction. For example, removal of hydrogen from hydrogen sulfide during oxidation changes the substance into sulfur or another oxidised product. Neutralisation concerns acid–base reaction, and displacement describes replacement of one element by another, so neither explains hydrogen removal here.
